The carbon balance at different forest management strategies on Tagel property (English)
Abstract [en]

Since the 19th century the concentration of CO2 in the atmosphere hasincreased by 40 percent as an effect of the use of fossil energy sources.Increased concentration of CO2 will likely lead to increased temperature,changes in precipitation, rising sea level and increased frequency of extremeweather like storm events. A step to reduce emissions of CO2 and mitigateclimate change, for the property of Tagel, can be to adopt new silviculturalstrategies and analyse which is the most effective. As a result of that, threescenarios was produced, business-as-usual (BAU), increased set aside landand energy. An introduction of windpower at Tagels estate (property) andeffects on carbon balance was also examined. By using the Heureka systemand LCA-analysis in this study, it showed that the scenario of increased setaside land was the most efficient way to reduce carbon dioxide (CO2)emissions for the analysed period of 100 years. The effect of substitution(replacing for example fossil fuel or energy consuming building materials,with renewable raw material such as biomass) didn’t give the result that waspredicted. It appears that the use of pulpwood is very important, if it goes tothe pulp industry no substitution effect occurs, but if all pulp will be used forbioenergy purposes, the energy scenario will be the best in terms of overallcarbon balance. The stored carbon in tree biomass over and in roots wasaffected by all scenarios. The soil carbon was almost the same for allscenarios. In the future the property of Tagel can still use the alternativeBAU as an effective way to mitigate climate change but then explore thepossibilities to use the pulp for bioenergy purposes instead and to set asidemore land at the property. This study considered to have high credibilitybecause the Heureka-analyses, LCA and the substitution model were carriedout by experts in area of research.
